Gtt R34 Engine Miss

[Jacko1987]

G day people I have a 98 gtt only owned it 2 months so I know nothing about these things starts fine idles fine but when I put the hammer down any where from 3500 to 5000 the power will drop out completely.. I thought it blew up .. But still is running... If I drive around just normally it's ok will only drop out when it feels like it have changed the fuel filter thought I might ask before I take it to the shop .. Standard intercooler and turbo 3 inch exhaust k&n air filter cheers

Coil packs.

Boost leak.

Random unknown mods we can't guess.

In that order.

Google those keywords. You can do it.

[Jacko1987]

Ok I'll check it out !

[Jacko1987]

Coil packs bit pricey any recommendations there

[Hadouken]

Hmmmm... I don't think anyone has ever tried anything other than oem coilpacks.

You know modification of r34's never really took off so I don't think there would be very strong aftermarket support for these cars.

Same on why there isn't much info about squeezing power out of them on the net.

Had a look on eBay anywhere from 350 to a grand

[Hadouken]

have you tried to google? I have and couldnt find anything. weird right

[Ben C34]

Giggle?

[Jacko1987]

Yea just have to keep on searching I guess

[Ben C34]

Where are you located?

Just remembered that I have a set of yellow jacket coils that you can try.

[Jacko1987]

In a remote town near cairns so probably no where near you

Don't buy cheap ones. When they fail again it will annoy you.

[Jacko1987]

Yea was looking at the yellow jacket ones or lash out a bit and go for the splitfire

[Kinks]

Splitfire. 100%.

[Jacko1987]

On they're way

great stuff. it's good practice to gap your plugs down to 0.8mm as well. Fresh coil packs should be firing no problem but reducing the gap makes it a bit easier on the ignition system.

you can buy pregapped plugs - BKR6E or BCPR6ES. Don't get the ones with -11 suffix, those are 1.1mm gap (and unfortunately more common). The ones without the suffix are 0.8mm.

you can put platinums/iridiums in if you get a good price but copper plugs are cheap and although you have to change them a bit more often it's good to have a look at them now and then (spark plugs tell a story about how your engine is running.. rich? lean? detonating? you'll see it on the plugs).

[Hadouken]

Say what?!

if they have -11 at the end then all you have to do is gap them down to 0.8.

If they are the same heat range as what is required then it makes zero difference!

I have gotten spark plugs that were meant to be gapped at 0.8 but were all over the shop, 0.7 - 1.0 on a batch of six

[Jacko1987]

Hahaha sounds like a pain

Hahaha sounds like a pain

You might as well sell your car now if you think that gapping spark plugs is a pain haha
